The specific embodiment
Below in conjunction with the practical implementation example, technical scheme of the present invention is further specified.
For solving described problem; A kind of manufacturing technology of high frequency material is provided; Minimum Copper Foil (shown in 2 among Fig. 1), Teflon (being polytetrafluoroethylene (PTFE)) resin (shown in 3 among Fig. 1), the glass fibre materials such as (shown in 1 among Fig. 1) of comprising of this material, Copper Foil is made up of at interior material crisscross glass fibre and the minimum polyflon that comprises between the Copper Foil of two sides as the constituent material on these two surfaces of material; Crisscross glass fibre is provided with for the bulk strength of reinforcing material; And used glass fibre is through reducing the processing of mechanical strength, is more conducive to processing when making the machining of glass fibre in subsequent manufacturing processes.
Glass fibre: glass is a kind of mixture, and its definition is " inorganic matter is after the high temperature melting mixes, and cooling becomes a kind of hard objects of noncrystalline kenel again ".Is drawn into filaments (Filament) as a textile fiber material in the development of new uses for success in 1939 formally entered the era of glass fibers.Glass fibre can be divided into two kinds of situation: a kind of is continous way, is used to weave glass cloth (Cloth or Fabric); Another kind is discontinuous fixed length formula, and slabbing glued together is called glass seat (Mat).Many glass fiber compositions are a branch of, and glass fiber is pressed warp-wise and broadwise interlacing Cheng Buzhuan one by one again, can obtain glass fabric.
Glass fabric used in copper-clad plate (English abbreviation: CCL) with printed wiring board (English abbreviation: PCB) on the industry in the market; Grade is that E-Grade is the electron level material, and it is the cloth shape material that is woven and be made into through a series of processing by the electronic-grade glass yarn.Glass fabric kind commonly used has 7628,2116,1080 etc., and it be a code name, the digital meaning of no essence.Detail specifications and forming as follows:
Figure BSA00000492595800041
Original glass fibre making process has: moisture regain, and------heald frame--is gone up weft yarn----boil off--grey cloth check--the silicon alkane processing-product inspection etc. of weaving cotton cloth to sizing to warping.Specify as follows:
Moisture regain: the extremely crisp and easy fracture of former glass, it is unusual when next operation, to be prone to produce filoplume, broken silk, broken yarn etc., handles so before coming into operation, will pass through moisture regain.The purpose is to allow a resurgence of moisture condenses into water film on the glass surface, glass fiber enhanced flexibility.
Warping: glass fabric be by warp thread (Warp) and weft yarn (Fill) be interwoven in length and breadth, because of the length of warp thread is very long, concerning the overall quality of cloth.So need the just cloth fabric width degree that weaves, with the raw yarn bought again in addition close interval arrange, just again with multireel raw yarn while parallel around wait weave cotton cloth on axle (Warp beam).Weft yarn then be directly on cop (Qvill or bobbin) going to weave cotton cloth gets final product.Because warp thread is through arrangement, and the yarn number is also many than weft yarn, so endurance strength is all good than weft yarn, thereby the stressed bigger direction of printed wiring board, should be advisable with warp-wise.
Sizing: sizing is the warp thread of arranging compiling again, and the processing (Sizing) that also will do a starching is called " slurry warp ".The purpose is to increase lubrication and reduce friction.These slurries also want destarch to handle after being made into cloth, to obtain clean glass surface.The Tension Control that this kind starching is handled is wanted SC, in case its fracture and influence the quality of cloth.The last warp thread of crossing slurry also will squeeze wheel (Nip Roll) through one and squeeze out redundant sizing agent, and then through after the oven dry of heat steam, can carry out the operation (Entering) of heald frame.
Heald frame: claim to combine yarn again.This action is every warp thread all to be penetrated the steel of taking the lead smash, and enables that (Loom) carries up and down in loom.Simultaneously, also need go up weft yarn, last weft yarn be original-pack living yarn again directly on cop; When weaving cotton cloth by " shuttle " or compressed-air actuated drive; Back and forth run quickly between warp thread, and form passing through and interweave one on the other with it, the preparation of weaving cotton cloth has been accomplished in various pre-treatments to this.
Weave cotton cloth: the method for weaving cotton cloth commonly used at present is the shuttle less loom method that drives the weft yarn yarn with compressed air or water.The method of weaving cotton cloth has multiple different types, but is used for the glass cloth of substrate, but from start to finish all only with a kind of flat weaving method soon through the weft yarn up and down weaving, the tool stability of the size of its cloth of flat weaving method is also least yielding, and weight and thickness are also the most even.
Boil off: claim to burn clean again.When glass fabric has woven completion, will to obtain clean glass fabric, make it can do further silicon coupling again and handle removing for the convenient slurry of temporarily coating of processing procedure.Because of glass fabric can not burn, but the organic matter that its adhering on surface can be decomposed into gas and break away from the glass fabric that so can obtain cleaning.Usually can be divided into the processing of two steps, at first be that continuous aerobic burns, and furnace temperature reaches 593~816 ℃, can burn 91~98% slurry, and then long-time low temperature batch processing; Next is that discontinuous batch of formula handled, and it is the glass cloth overline to be wrapped on the metal cylinder of porous put in the baker again, in 260 ℃~371 ℃, burns 55~80 hours, and the organic matter in the cloth is not approachingly had by further evaporating into fully.Batch formula K cryogenic treatment method is slowly left grease and fugitive constituent in the slurry, unlikelyly causes great amount of heat energy to pour in and generates the reduction that tensile strength should be arranged.
Grey cloth check: in this step, adopt the mode of desk checking, confirm whether the quality of glass fabric meets standard fully, for incongruent product, need choose, or graduation is handled.
Silicon alkane is handled: claim silicon alkane coupling processing again.Because glass surface is very smooth, other material such as water, resin etc. are not easy glass surface or fiberglass surfacing wetting well, just can not combine well between resin and the glass fibre like this, thereby produce quality problem.Silane treated glass fiber surface is coated with a "coincidence" of the cortex, so that the resin in addition to the original mechanical properties, and then provide a molecular level "bond relay", drastic changes in temperature to maintain a combination of both strength , it can be called "adhesion promoter" (Adhesion? promoter).If silicon alkane processing layer can cover glass the surface, make its unlikely adhesive force that loses with resin under the encirclement of moisture content, and then can keep the insulating properties of dielectric material.This kind coupling agent is essentially a kind of material that blendes together (Hybrid Material), and an end has the very strong organic functional base of a kind of reagency in its molecule, and the other end then is the functional group of inorganic nature, and is middle then be the trunk of silicon alkane.The in-between monolayer of this kind " coupling epithelium " has promptly formed at the film of B-stage intact man-hour.If the above silanes which compound coupling agent such as molecular structure: X-Si-R-(OCH3) 3, X is amino group, an epoxy group, and styrene.
Reduction glass fibre mechanical strength One of processing methodFor: the mechanical strength that adopts the method reduction glass fibre of long-time high-temperature baking.
We know that the composition that constitutes glass mainly contains following: SiO 2, Al 2O 3, B 2O 3, CaO, MgO, R 2O, the produced glass of normal condition, these compositions can be mixed equably, form whole uniformly formation, promptly belong to the glass of not phase-splitting.As glass is heat-treated under 400~650 ℃ of temperature, it can be transformed into Na 2O-B 2O 3With SiO 2Two phases, i.e. the glass of phase-splitting.After the glass process phase-splitting heat treatment, its mechanical strength can descend, and becomes more crisp, thereby when machining, is more conducive to be cut disconnected.One of method of long-time high-temperature baking is minimum to comprise following processing: under 400 ℃~650 ℃ temperature conditions, toasted 90~120 hours; Two of the method for long-time high-temperature baking minimumly comprises following processing: under 200 ℃~400 ℃ temperature conditions, toasted 200~400 hours.Different heat treatment degrees, the fragility of glass fibre are also different, and temperature is high more, the processing time is long more, and then fragility is big more, when machining then easy more be cut disconnected; And temperature is low more, the processing time is short more, and then pliability keeps fully more, when machining then difficulty be cut disconnected.After such high-temperature baking processing, the mechanical strength of glass fibre can descend 20%~80%.Above-mentioned treatment conditions can also be divided into several kinds of class, to obtain the glass fibre of different mechanical strength sizes.
Reduction glass fibre mechanical strength Two of processing methodFor: the diameter of described glass fibre is controlled between 0.5um~5um, to reduce the mechanical strength of glass fibre.
The diameter of wall scroll glass fibre is big more, and then its mechanical strength is also just big more, and when machining, then difficulty is cut disconnectedly more, causes the possibility of quality problem just big more after processing; The diameter of wall scroll glass fibre is more little, and then its mechanical strength is also just more little, when machining, then is cut disconnectedly more easily, causes the possibility of quality problem just more little after processing.Adopt less glass fibre spelling to become the glass fiber bundle of identical size; Or adopt more glass fibre bar number to be placed in the material; Can obtain that final mechanical strength does not descend or descend on a small quantity but but be more conducive to the Teflon high frequency material of machining (the meaning here is meant: when materials such as resin, glass fibre, Copper Foil are processed high frequency material sheet material; Or after these high frequency material sheet materials processed printed wiring board, this this high frequency material or printed wiring board were not easy to occur bending and deformation etc.).With the glass fiber diameter that is fit to size, the diameter of glass fibre is controlled between 0.5um~5um, make and the requirement that both can satisfy overall mechanical strength can improve the required required precision of machining again.
Reduction glass fibre mechanical strength Three of processing methodFor: the diameter of described glass fibre is controlled between 0.5um~5um, and adopts the method for long-time high-temperature baking, to reduce the mechanical strength of glass fibre.The method be above-mentioned " One of processing method" and " Two of processing method" combine and draw, when a kind of in above-mentioned any one method all can not satisfy the demand of machining accuracy, adopt the method for two kinds of method superpositions, can further improve problem, to satisfy the technical need of different levels.
Reduction glass fibre mechanical strength Four of processing methodFor: the diameter of described glass fibre is controlled between 0.5um~5um, and again fiberglass surfacing is stung the erosion alligatoring after adopting long-time high-temperature baking, to reduce the mechanical strength of glass fibre.The method of fiberglass surfacing being stung the erosion alligatoring has two kinds: a kind of is to sting the erosion minimum composition that contains fluorine of chemicals that glass fibre adopted; Another kind is to adopt the chemicals with acidity that fiberglass surfacing is stung erosion, thereby makes original more smooth fiberglass surfacing become coarse.Be described in detail below:
Sting etching method one: adopt the chemicals that contains fluorine that fiberglass surfacing is stung erosion, thereby make original more smooth fiberglass surfacing become coarse.Fluorine-containing material can corrode the material of category of glass; Thereby cause the effect of etching; And hydrogen fluoride is the most frequently used and more facile a kind of material; Hydrogen fluoride and all can the material of category of glass be corroded with the mixture of other materials is so containing of stinging erosion glass fibre adopted minimumly in the fluorine chemistry medicine comprises hydrofluoric composition and promptly can realize the erosion of stinging to glass.Stinging erosion fluorine-containing chemicals that glass fibre adopted can be to be in liquid material, also can be the material that is in gaseous state, if during liquid, needs glass fiber is immersed in the fluorine-containing liquid, to realize the erosion of stinging to glass fibre; If during gaseous material, need glass fiber is placed fluorine-containing gas, to realize the erosion of stinging to glass fibre.The benefit that adopts gaseous material to sting erosion is, stings after erosion finishes, and can dry, and that glass fibre is still is dry; If when adopting liquid to sting erosion; Glass fibre or glass fabric itself understood impregnation and adhered to liquid; The next treatment process that can be transported to these liquid causes the pollution of operation down, and in the process of transporting, the fluorine-containing material that is contained in the liquid can continue to sting the erosion glass fibre; Cause that to sting erosion inhomogeneous or out of control, be unfavorable for producing and steadily carry out.The more important thing is; Glass fibre is not easy to be soaked into by liquid; Local location maybe by soaked with liquid to and cause stinging the erosion poor or basic just not stinging lost, such result does not play the effect of processing, the quality of product also is not assurance.If adopt gaseous material to sting the erosion glass fibre, when glass fibre is placed in the gaseous state fluorine-containing material, will be snapped erosion at once, there is not the problem that can't soak into.In addition, adopt the gaseous state fluorine-containing material to sting the erosion glass fibre, can also make that the surface of glass fibre is more coarse, thereby make the adhesion between glass fibre and the resin more strengthen.Strict control is stung the degree of depth that erosion advances fiberglass surfacing accounting between 1%~20% the scope of glass fiber diameter, can obtain alligatoring effect preferably, and can not cause other problems.Shown in 1 among Fig. 2, the 1st, do not pass through the sketch map of segment of the glass fibre of roughening treatment, its surface is smooth; As shown in Figure 3,1 passed through roughening treatment after, its surface becomes more coarse; A and b are illustrated respectively in the erosion amount of stinging of upper and lower two positions of fiberglass surfacing; Under the normal production conditions, a is to equate basically with b, and this stings the erosion amount and is controlled between 0.02 micron to 2 microns and gets final product.In process of production, the gaseous state fluorine-containing material need cooperate with suitable agitating or blowing, so that glass fibre is in the uniform gaseous state fluorine-containing material of the concentration space, is beneficial to the carrying out that stings the erosion reaction simultaneously.Also have, fluorine-containing material is a poisonous and harmful substance, cannot directly be discharged in the air or in the external environment, needs to cooperate with enough recovery systems to accomplish such purpose.
Sting etching method two: adopt chemicals that fiberglass surfacing is stung erosion with acidity.We know that the composition that constitutes glass mainly contains following: SiO 2, Al 2O 3, B 2O 3, CaO, MgO, R 2O, the produced glass of normal condition, these compositions can be mixed equably, form whole uniformly formation, promptly belong to the glass of not phase-splitting.As glass is heat-treated under 400~650 ℃ of temperature, it can be transformed into Na 2O-B 2O 3With SiO 2Two phases, i.e. the glass of phase-splitting.After the glass process phase-splitting heat treatment, its mechanical strength can descend, and becomes more crisp, thereby when machining, is more conducive to be cut disconnected.Make the granularity of glassy phase of glassy phase and the silicic acid matter of boronic acid containing and alkali metal oxide be about the order of magnitude of tens dusts, form two kinds of fine structures that glassy phase mixes, such glass under 90 ℃ with processing such as hydrochloric acid and hot water, the Na of solubility 2O-B 2O 3Glassy phase is dissolved out, and remaining just becomes with SiO 2Be Main Ingredients and Appearance, it is the glass with micropore shape that has kept original shape of glass, and its surface promptly has coarse characteristic.Certainly, also can adopt and contain sulfuric acid or other sour solution is done this processing, but processing speed can be slow.According to use occasion and needs, control the variation of heat treatment time and temperature etc., can change aperture, pore size distribution, the pore volume of micropore, process the micropore of aperture homogeneous.Excess processes can cause the Na of solubility in the whole glass fibre 2O-B 2O 3Glassy phase all is snapped eating away, makes glass fibre become the cellular strand shape material as the sponge shape, and not only mechanical strength descends greatly and cannot meet the demands; And the as easy as rolling off a log moisture absorption and storage pollutant; In the manufacture process of printed wiring board, the moisture absorption can cause printed wiring board itself to have steam, can run into processing such as water and need baking in the mill in the journey repeatedly; Thereby water evaporates goes out to cause problems such as plate bursting, layering during baking, and a large amount of quality problem will be following.Strict control is stung the degree of depth that erosion advances fiberglass surfacing and is being accounted between 1%~20% the scope of glass fiber diameter; Both can obtain coarse fiberglass surfacing; Can guarantee again follow-up quality problem not to take place, thereby meet the use of printed wiring board industry.Shown in 1 among Fig. 2, the 1st, do not pass through the sketch map of segment of the glass fibre of roughening treatment, its surface is smooth; As shown in Figure 3,1 passed through roughening treatment after, its surface becomes more coarse; A and b are illustrated respectively in the erosion amount of stinging of upper and lower two positions of fiberglass surfacing; Under the normal production conditions, a is to equate basically with b, and this stings the erosion amount and is controlled between 0.02 micron to 2 microns and gets final product.Employing has acid chemicals fiberglass surfacing is stung erosion, thereby makes original more smooth fiberglass surfacing become coarse.Sting the material that the erosion chemicals with acidity that glass fibre adopted can adopt the composition that comprises hydrogen chloride, also can adopt to comprise sulfuric acid (H 2SO 4) or other sour compositions, or by the material that more than one acid mixes, in stinging the erosion process, need to cooperate with suitable heating, sting the process of erosion glass fibre to quicken alligatoring.Through stinging erosion alligatoring glass fibre afterwards; Its mechanical strength can further descend; And because there is more coarse shape in fiberglass surfacing; The local stress that matsurface produces when machining can so that glass fibre be more prone to be cut disconnected, thereby obtain better machining accuracy.
Reduction glass fibre mechanical strength Five of processing methodFor: the diameter of described glass fibre is controlled between 0.5um~5um, and fiberglass surfacing is stung the erosion alligatoring, to reduce the mechanical strength of glass fibre.With fiberglass surfacing sting the erosion alligatoring method with above-mentioned Four of processing methodIn " stinging etching method one " describe.
Above content is to combine concrete preferred implementation to the further explain that the present invention did, and can not assert that practical implementation of the present invention is confined to these explanations.For the those of ordinary skill of technical field under the present invention, under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to protection scope of the present invention.
